A stopping device (10) for a segmented roll in a fiber-web machine for assisting the stopping of the rotation of one or more roll segment(s) (52) of the segmented roll (50) has at least one braking device (12), by means of which the roll segment (52) can be stopped, and at least one surface contact member (14, 14′), which surface contact member is connected to said braking device, and the stopping device further comprises actuators (16) for optionally bringing/releasing the surface contact member into/from surface contact with the shell of one or more roll segment(s) (52). The invention also relates to a segmented roll assembly (60) in a fiber-web machine, in which the segmented roll (50) comprises at least two, independently from one another rotatable roll segments (52) that are located end-to-end substantially in the transverse direction of the fiber-web machine.
